CO₂ Allowance & Electricity Price Interaction: Impact on Industry's Electricity Purchasing Strategies in Europe

Core Content

This document explores the interaction between CO₂ allowance prices and electricity prices in the European Union, focusing on how this relationship influences the electricity purchasing strategies of energy-intensive industries (EII). It provides a comprehensive analysis of the EU Emissions Trading Scheme (EU ETS) and its economic implications, as well as the various electricity pricing mechanisms and contractual strategies used by industrial users.

Main Drivers of CO₂ Prices

• The EU ETS, introduced in 2005, sets a cap on CO₂ emissions for over 11,500 installations across the EU-25.
• CO₂ allowances are initially distributed for free, which may affect how much of the allowance cost is passed through to electricity prices.
• The price of CO₂ allowances can fluctuate based on market dynamics, including supply and demand, and may influence electricity generation and purchasing decisions.

Electricity Price Components

• The actual cost components of electricity generation include natural gas, coal, and fuel oil prices.
• These fuel prices are key determinants of generation costs and, therefore, electricity market prices.
• CO₂ allowance prices can be passed through to electricity prices, though the extent varies by country and market structure.

CO₂ Pass-through to Electricity Prices

• Theoretical models suggest that CO₂ prices should be reflected in electricity prices as a marginal cost.
• Empirical studies show that in some countries, such as Germany and the Netherlands, CO₂ pass-through rates range from 39% to 80%.
• The pass-through rate depends on contractual agreements, regulatory frameworks, and the elasticity of demand.

Electricity Market Structures

• European electricity markets are not uniform and feature various pricing mechanisms.
• These include:
  • Market prices set by the marginal generator or bidder.
  • "Screen prices" for baseload needs.
  • Annual contracts and regulated tariffs.
• Different countries have different market structures, which influence how CO₂ prices are incorporated into electricity costs.

Industrial Electricity Purchasing Strategies

• Industrial users may adopt different strategies to manage electricity costs and CO₂ price exposure:
  • Direct purchases on the market (both day-ahead and forward prices).
  • Long-term supply contracts with suppliers.
  • Self-generation with or without third-party involvement.
• These strategies vary depending on the regulatory environment and the industrial user's ability to negotiate.

Risk Management and Price Volatility

• Electricity prices are more volatile than other fuel commodities.
• CO₂ price volatility may further contribute to this.
• Industrial users can manage price risk through:
  • Market derivatives (e.g., futures, forwards).
  • Energy management companies that offer risk mitigation services.
  • Risk-sharing agreements with suppliers.
• Some strategies allow industrial users to pay less than wholesale prices by sharing costs or risks with generators.

Policy Implications

• Governments should avoid using CO₂ allocation as a tool for other energy policy goals.
• They should provide long-term visibility on emission targets to encourage investment in cleaner technologies.
• Auctioning allowances could reduce political issues and ensure a more level playing field.
• Revenue from allowances could be used to support energy efficiency measures or offset costs for specific industries.
• The goal of emissions trading should be to achieve cost-effective CO₂ reductions, not to pursue other energy policy objectives.

Key Findings

• CO₂ prices are becoming an important cost component for electricity generation.
• Pass-through of CO₂ prices to electricity prices is not universal and depends on market structure and contracts.
• Industrial purchasing strategies are evolving in response to increased price volatility and the need for cost predictability.
• Self-generation and risk-sharing are emerging as viable options for managing electricity and CO₂ costs.
• Policy clarity and long-term stability are crucial for fostering investment in low-carbon technologies.

Conclusion

The interaction between CO₂ allowance prices and electricity prices is a critical factor in shaping the electricity purchasing strategies of energy-intensive industries in Europe. As CO₂ prices become more significant, industrial users are adapting through various contractual and operational strategies. Governments should ensure that emissions trading systems are designed to reflect the true cost of emissions, support investment in cleaner technologies, and manage distributional impacts effectively.
